Abstract

Materials characterization is important when we want to determine features of different surfaces that are used in many areas. Tribological parameters help to this type of characterization, mainly for worn surfaces. There are techniques with complex mechanisms that allow to obtain these parameters and to observe all the surface characteristics. We are using an atomic force microscope and a roughness tester in order to characterize femoral head surfaces and component parts made of steel, titanium alloys or CoCr alloys..
